When I massaged the code to do multiple gas pressures in commit e1b880f4
("Profile support for multiple concurrent pressure sensors") some of the
Y offsetting code got cut out as being too specific to the old
o2pressure code.
But I removed a bit too much, leaving the label (gas name) and number
(gas pressure) overlapping.
This should fix it.
If we really care about multiple gas pressure labels overlapping each
other, we'll have to revisit this code, but the old two-gas case didn't
do a very good job either (both that old code - and this new version -
can look very good in particular cases, but there are cases where it
won't work so well).
So we may need to revisit this eventually, but this gets it looking fine
for the normal cases.

This finally handles multiple cylinder pressures, both overlapping and
consecutive, and it seems to work on the nasty cases I've thrown at it.
Want to just track five different cylinders all at once, without any
pesky gas switch events? Sure, you can do that. It will show five
different gas pressures for your five cylinders, and they will go down
as you breathe down the cylinders.
I obviously don't have any real data for that case, but I do have a test
file with five actual cylinders that all have samples over the whole
course of the dive. The end result looks messy as hell, but what did
you expect?
HOWEVER.
The only way to do this sanely was
- actually make the "struct plot_info" have all the cylinder pressures
(so no "sensor index and pressure" - every cylinder has a pressure for
every plot info entry)
This obviously makes the plot_info much bigger. We used to have
MAX_CYLINDERS be a fairly generous 8, which seems sane. The planning
code made that 8 be 20. That seems questionable. But whatever.
The good news is that the plot-info should hopefully get freed, and
only be allocated one dive at a time, so the fact that it is big and
nasty shouldn't be a scaling issue, though.
- the "populate_pressure_information()" function had to be rewritten
quite a bit. The good news is that it's actually simpler now, although
I would not go so far as to really call it simple. It's still
complicated and suble, but now it explicitly just does one cylinder at
a time.
It *used* to have this insanely complicated "keep track of the pressure
ranges for every cylinder at once". I just couldn't stand that model
and keep my sanity, so it now just tracks one cylinder at a time, and
doesn't have an array of live data, instead the caller will just call
it for each cylinder.
- get rid of some of our hackier stuff, like the code that populates the
plot_info data code with the currently selected cylinder number, and
clears out any other pressures. That obviously does *not* work when you
may not have a single primary cylinder any more.
Now, the above sounds like all good things. Yeah, it mostly is.
BUT.
There's a few big downsides from the above:
- there's no sane way to do this as a series of small changes.
The change to make the plot_info take an array of cylinder pressures
rather than the sensor+pressure model really isn't amenable to "fix up
one use at a time". When you switch over to the new data structure
model, you have to switch over to the new way of populating the
pressure ranges. The two just go hand in hand.
- Some of our code *depended* on the "sensor+pressure" model. I fixed all
the ones I could sanely fix. There was one particular case that I just
couldn't sanely fix, and I didn't care enough about it to do something
insane.
So the only _known_ breakage is the "TankItem" profile widget. That's
the bar at the bottom of the profile that shows which cylinder is in
use right now. You'd think that would be trivial to fix up, and yes it
would be - I could just use the regular model of
firstcyl = explicit_first_cylinder(dive, dc)
.. then iterate over the gas change events to see the others ..
but the problem with the "TankItem" widget is that it does its own
model, and it has thrown away the dive and the dive computer
information. It just doesn't even know. It only knows what cylinders
there are, and the plot_info. And it just used to look at the sensor
number in the plot_info, and be done with that. That number no longer
exists.
- I have tested it, and I think the code is better, but hey, it's a
fairly large patch to some of the more complex code in our code base.
That "interpolate missing pressure fields" code really isn't pretty. It
may be prettier, but..
Anyway, without further ado, here's the patch. No sign-off yet, because I
do think people should look and comment. But I think the patch is fine,
and I'll fix anythign that anybody can find, *except* for that TankItem
thing that I will refuse to touch. That class is ugly. It needs to have
access to the actual dive.
Note how it actually does remove more lines than it adds, and that's
despite added comments etc. The code really is simpler, but there may be
cases in there that need more work.
Known missing pieces that don't currently take advantage of concurrent
cylinder pressure data:
- the momentary SAC rate coloring for dives will need more work
- dive merging (but we expect to generally normally not merge dive
computers, which is the main source of sensor data)
- actually taking advantage of different sensor data from different
dive computers
But most of all: Testing. Lots and lots of testing to find all the
corner cases.

Now that the cylinder pressures are more generalized, we should show
them even for non-CCR dives if we have them. The most notable example
would be having separate pressure transmitters for both cylinders in a
sidemount setup. The code no longer really depends on any CCR logic.
NOTE! This is still preparatory work, in that this is one part of
supporting multiple simulataneous cylinder pressures, but we are still
lacking in other departments (eg properly filling those fields in when a
dive computer exports multiple pressure sensors etc).

This is a very timid start at making us actually use multiple sensors
without the magical special case for just CCR oxygen tracking.
It mainly does:
- turn the "sample->sensor" index into an array of two indexes, to
match the pressures themselves.
- get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index},
since a CCR dive should now simply set the sample->sensor[] indices
correctly instead.
- in a couple of places, start actually looping over the sensors rather
than special-case the O2 case (although often the small "loops" are
just unrolled, since it's just two cases.
but in many cases we still end up only covering the zero sensor case,
because the CCR O2 sensor code coverage was fairly limited.
It's entirely possible (even likely) that this migth break some existing
case: it tries to be a fairly direct ("stupid") translation of the old
code, but unlike the preparatory patch this does actually does change
some semantics.
For example, right now the git loader code assumes that if the git save
data contains a o2pressure entry, it just hardcodes the O2 sensor index
to 1.
In fact, one issue is going to simply be that our file formats do not
have that multiple sensor format, but instead had very clearly encoded
things as being the CCR O2 pressure sensor.
But this is hopefully close to usable, and I will need feedback (and
maybe test cases) from people who have existing CCR dives with pressure
data.

There was a bug in the old code due to confusion between minutes
and seconds as the unit of the time axis. But rather than limiting
the time for the last handle in terms of the time axis (which
potentially includes long deco and allowing that for bottom time
quickly leads to dives many many hours long) limit it to 150%
of the previous bottom time.

Wfloat-conversion enabled for C++ part of the code
Fix warnings raised by the flag using lrint
Original issue reported on the mailing list:
The ascent/descent rates are sometimes not what is expected.
E.g. setting the ascent rate to 10m/min results in an actual
ascent rate of 9m/min.
This is due to truncating the ascent rate preference,
then effectively rounding up the time to reach each stop to 2s intervals.
The result being that setting the ascent rate to 10m/min
results in 20s to ascend 3m (9m/min), when it should be exactly 18s.

When moving the last handle of a dive (in the planner, in dive add, or
when editing a dive), we rescaled the time axis whenever our idea of the
maximum duration that we should show changed. That lead to the odd
situation that you couldn't get to certain dive durations with the
visual editor (e.g. 64 minutes) because just as you approach that time
the scale changes and the dive duration jumps past the desired value.

When painting the tankbar the function triggers on change in cylinder index,
as a result the new gascolour are changed at the next sample time point.
On a divecomputer with a reasonable fast sample rate the 2-3s offset are hardly
noticable, especially on a longer dive.
For divecomputers with slow sample rate the 10-30s offset are clearly visible.
This is fixed by start painting the new gascolour at the time point of the switch event rather than the time point of the next sample.
